Abstract:
A capacitor includes a bottom electrode and a top electrode positioned above the bottom electrode. The top electrode and the bottom electrode are conductively coupled to one another. A middle electrode is positioned between the bottom electrode and the top electrode. A lower dielectric layer is positioned between the bottom electrode and the middle electrode. An upper dielectric layer is positioned between the middle electrode and the top electrode. A first contact is conductively coupled to the top electrode. A second contact is conductively coupled to the middle electrode.
